Heavy-duty Vehicle and Engine Greenhouse Gas Emission Regulations
Marginal note:Calculation of average standard
22 (1) Subject to subsection (6), a company must calculate the fleet average CO2 emission standard for a given model year, expressed in grams of CO2 per mile and rounded to the nearest gram of CO2 per mile, for its fleet of Class 2B and Class 3 heavy-duty vehicles and cab-complete vehicles — excluding those that are vocational vehicles or incomplete vocational vehicles — using the formula
(Σ (A × B)) ÷ C
where
- A
- is the CO2 emission target value calculated for each vehicle subconfiguration in the fleet using the applicable formula set out in subsection (2) and rounded to the nearest gram of CO2 per mile;
- B
- is the number of vehicles of that vehicle subconfiguration in the fleet; and
- C
- is the number of vehicles in the fleet.
Marginal note:Vehicle subconfiguration
(2) Subject to subsection (4), the CO2 emission target value for each vehicle subconfiguration in a fleet must be calculated using the applicable formula set out in one of the following paragraphs:
(a) for vehicles that are equipped with a spark-ignition engine, the formula set out in column 2 of the table to this paragraph for the model year set out in column 1, where WF is the work factor for each vehicle subconfiguration, calculated using the formula set out in subsection (3) and rounded to the nearest pound;
Column 1 Column 2 Item Model Year CO2 Emission Target (grams/mile) 1 2014 (0.0482 × WF) + 371 2 2015 (0.0479 × WF) + 369 3 2016 (0.0469 × WF) + 362 4 2017 (0.0460 × WF) + 354 5 2018 to 2020 (0.0440 × WF) + 339 6 2021 (0.0429 × WF) + 331 7 2022 (0.0418 × WF) + 322 8 2023 (0.0408 × WF) + 314 9 2024 (0.0398 × WF) + 306 10 2025 (0.0388 × WF) + 299 11 2026 (0.0378 × WF) + 291 12 2027 and subsequent (0.0369 × WF) + 284 (b) for vehicles that are equipped with a compression-ignition engine or that operate without an internal combustion engine, the formula set out in column 2 of the table to this paragraph for the model year set out in column 1, where WF is the work factor for each vehicle subconfiguration, calculated using the formula set out in subsection (3) and rounded to the nearest pound.
Column 1 Column 2 Item Model Year CO2 Emission Target (grams/mile) 1 2014 (0.0478 × WF) + 368 2 2015 (0.0474 × WF) + 366 3 2016 (0.0460 × WF) + 354 4 2017 (0.0445 × WF) + 343 5 2018 to 2020 (0.0416 × WF) + 320 6 2021 (0.0406 × WF) + 312 7 2022 (0.0395 × WF) + 304 8 2023 (0.0386 × WF) + 297 9 2024 (0.0376 × WF) + 289 10 2025 (0.0367 × WF) + 282 11 2026 (0.0357 × WF) + 275 12 2027 and subsequent (0.0348 × WF) + 268
Marginal note:Work factor
(3) The work factor for each vehicle subconfiguration is calculated using the formula
0.75 × (GVWR – curb weight + xwd) + 0.25 × (GCWR – GVWR)
where
- GVWR
- is the GVWR as defined in subsection 1(1), expressed in pounds;
- curb weight
- is the curb weight as defined in subsection 1(1), expressed in pounds;
- xwd
- is 500 pounds if the vehicle has four-wheel drive or all-wheel drive and is 0 pounds for all other vehicles; and
- GCWR
- is the GCWR as defined in subsection 1(1), expressed in pounds.
Marginal note:Alternative target value calculation — 2016 to 2018 model years
(4) For vehicles of the 2016 to 2018 model years, a company may, instead of calculating the CO2 emission target value in accordance with subsection (2), elect to calculate that target value for each of those model years using the formula set out in either of the following paragraphs, whichever applies:
(a) for vehicles that are equipped with a spark-ignition engine,
(0.0456 × WF) + 352
where
- WF
- is the work factor for each vehicle subconfiguration, calculated using the formula set out in subsection (3) and rounded to the nearest pound;
(b) for vehicles that are equipped with a compression-ignition engine or that operate without an internal combustion engine,
(0.0440 × WF) + 339
where
- WF
- is the work factor for each vehicle subconfiguration, calculated using the formula set out in subsection (3) and rounded to the nearest pound.
(5) [Repealed, SOR/2018-98, s. 24]
Marginal note:Grouping subconfigurations into configurations
(6) A company may group vehicle subconfigurations of Class 2B and Class 3 heavy-duty vehicles and cab-complete vehicles — excluding those that are vocational vehicles or incomplete vocational vehicles — within a vehicle configuration for the purpose of calculating the fleet average CO2 emission standard if
(a) the vehicles of each subconfiguration have the same test weight, GVWR and GCWR, and the work factor and target value are calculated assuming a curb weight equal to two times the test weight minus the GVWR; or
(b) the lowest target value of a vehicle subconfiguration is used for all vehicle subconfigurations.
